Investigators at the National Highway Traffic Safety Administration (NHTSA) are once again turning their gaze to the Toyota Tundra. The regulatory group's study of the popular pickup's steering mechanism already led to a recall of 790,000 units last year, which included models like the 2002-2004 Sequoia and 2001-2002 4Runner.

NHTSA's new inquiry affects some 95,000 2004 model year Tundras built after September 30, 2003, and centers on the potential failure of front suspension ball joints. The potentially faulty part has been blamed for an accident resulting in an injury.
